It probably does but here is my reasoning for a new file. 1. The latest FREEBSD master has support for the lpc32xx where the 9.2 branch did not. It's easy to port the already existing code (i.e. MAC driver, OHCI, MMC, etc...). 2. The ohci_lpc.c driver was not using FREEBSD's bus resources which was different from other drivers. 3. The logic to probe, attach, detach, suspend, and resume was taken from the ohci_lpc.c driver but used the hardware access functions provided by the latest FREEBSD.
Logically the drivers are the same but the lpc_ohci.c driver uses the FREEBSD LPC interface (with the caveat of the "struct usb_otg_transceiver" interface). Ideally the LPC USB OTG I2C code should be moved to an I2C driver. An USB OTG transceiver driver should be created to probe for the ISP1301/STOTG04E devices. However, I did not go to this level.
